DISINFECTING APPARATUS.

Application filed March 29, 1897. Serial No. 6291761. (No model.)

ants by pneumatic pressure and which may be actuated by the manual operation of a simple I hand-pull.

To this end the invention consists in the combination, with a supply-reservoir adapted to contain the desired supply of the liquid disinfectant, of an auxiliary reservoir connected with the lower part of the supply-reservoir, a discharge-conduit connected 4with the auxiliary reservoir and rising above the liquid-level of the supply-reservoir, an airforcing device consisting of a compressible elastic bulb connecting with the auxiliary reservoir, and a lever arranged to compress and discharge said bulb and create a pneumatic pressure in the auxiliary reservoir when the hand-pull is operated.

It consists, further, in the arrangement and combination of parts and details herein shown and described, and speciiically pointed out in the claims.

The accompanying drawing shows a sectional elevation of my improved device.

In said drawing, A indicates the supplyreservoir of sufficient size to contain the requisite supply of liquid disinfectant and which may be secured in any suitable position above the level of the closet-bowl or other object to which the disinfecting material is to be supplied. The auxiliary reservoir B is arranged in the lower part of the reservoir A and communicates therewith by means of the small opening b in the side of the reservoir B, so that the auxiliary reservoir B will always be completely filled so long as the liquid-level in the reservoir A does not fall below the top of the auxiliary reservoir B. The dischargeconduit C enters the auxiliary reservoir B through its top and extends upwardly above the normal high level of the liquid in the reservoir A. the reservoir B is prevented under normal conditions until the apparatus is put into operation, as hereinafter described. The up v per part of the discharge-conduit C is beiit and carried over the top of the measuringchamber D, which, as shown, is partially filled with suitable fibrous material, such as cotton. The pipe E connects with the lower part of the chamber D, and through it the liquid disinfectant is carried to the point of application.

F is a hollow rubber ball or bulb formed of some compressible material and preferably of rubber. The pipe G connects the interior of the bulb F with the upper part of the auxiliary reservoir. ranged on top of the reservoir A, as shown,

and is surrounded by an open coil helical spring H. The spring is held in place by the centering-bosses h, one of which is secured to the top of the reservoir A and the other of which is secured to the under side of the lever I. The under side of the latter is provided with a convex projection or bearingsurfacei, which rests on the top of the bulb F. The lever I is pivoted at t' to the standard J. Standards K (only one of which is shown in the drawing) are secured to the opposite end of the reservoir A and serve as guides for the free end of the lever I. The free end of said lever is connected by an ordinary chain or rope to the hand-pull L. A cup a surrounds the measuring-chamber D and the filling-opening a. The removable cover a2 is provided to exclude dust from the apparatus. The spring II serves not only to hold the bulb F in position, but also operates to return the lever to the position shown in the drawing when the hand-pull L is released.

The operation of the device is as follows: When the reservoir A is filled with the liquid disinfectant, it will iiow through the opening b, lling the auxiliary reservoir B and rising in the pipes C and G to the level of the liquid in the reservoir'A. To operate the machine, the l1and-pnll L is pulled downwardly, carry'- ing with it the lever I, which will compress the bulb F. The compression of the bulb F will create sufficient pressure behind the liquid in the reservoir B and pipe C to cause In this manner any discharge froni The bulb F is preferably arthe same to iiow over into the measuringchamber D. The parts are preferably so adjusted and proportioned that considerablymore liquid will kbe forced through the pipe C than is sufficient to iill the chamber D, and

the surplus will flow into the cup a and again enter the reservoir A through the opening a. As the pressure produced by the compression of the bulb F is exerted suddenly and as the opening from the chamber D is nearly closed by the cotton or other restricting substance, the amount of disinfectant received and held by the measuring-chamber at each operation of the apparatus is practically constant under xed conditions and may be varied as desired by simply varying the amount of the packing d. The liquid discharged in the chamber D will percolate slowly through the packing into the pipe E and will be carried thereby to the point at which it is desired to apply the disinfecting liquid. Upon the release of the pull L the spring I-I will return the lever I toits original position.

Ido not claim herein, broadly, the combi.

nation of the parts herein shown in combination with any form of air-forcing device. Such combination forms the subject-matter of my application, Serial No. 622,696, tiled February 9, 1897, and I make no claim herein to the device shown, except in combination with thespecial form of air-forcing device shown, and specifically designated in the claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is Y l. In a disinfecting apparatus for manual operation, the combination of a supply-reservoir, a smaller auxiliary reservoir secured to the lower portion thereof, an opening between the lower part of the supply-reservoir and the auxiliary reservoir, a discharge-conduit leading from the auxiliary reservoir and risA ing above the liquid-level of the supply-reservoir, a compressible elastic bulb carried on the top of the supply-reservoir, a tube or conduit connecting the interior of said bulb with the interior of the auxiliary reservoir, a lever resting the upward movement of the lever,v

substantially as shown and described.
